Do enzymes need to be replaced?

I'm curious to know, do enzymes need to be replaced within the body? If so, how often do they need to be replenished, and what factors influence their turnover rate? Additionally, are there any dietary or lifestyle changes that can help support optimal enzyme function and reduce the need for replacement? It's important to understand the role of enzymes in maintaining our health, and I'm eager to learn more about their dynamics within the body.
